"Passed?" Fan Wuxian asked with some emotion.

At this time, his heart was still very complicated. On the one hand, he is very enthusiastic about the large aircraft project, but on the other hand, he is also a little worried about whether the project can achieve his intended purpose, after all, such a huge plan, to mobilize the strength of the whole country to complete, is definitely not a trivial matter, even if his follow-up funds can be continuously supplied, but technology is always the most critical.

The slightest mistake can lead to the failure of a large aircraft project, let alone a perfect finished product within ten years, and it can be mass-produced, which is an impossible task in the eyes of any country.

However, Fan Wuxian feels that the existence of Chinese is to create miracles, and the large aircraft project will naturally be no exception.

Early the next morning, Fan Wuxian went to Boss Zhu's side and discussed with the relevant persons in charge of various ministries and commissions of the State Council about the formation of a leading group for the large aircraft project.

Because this project is so big, it can be said that the amount of work far exceeds that of the Three Gorges Project, and the manpower and material resources used are the largest since the founding of the People's Republic of China.

Boss Zhu personally served as the leader of the project team. This project team is mainly responsible for the coordination of all aspects, so that it can cooperate with the China Aviation Manufacturing Group Corporation, which is about to be established with Fan Wuzhi as the chairman, to complete this large-scale project.

"In short, we must work together to build our own large aircraft within 10 years, and we must be able to gain a foothold in the international arena and have a market." That's what Boss Zhu said.

The expert group of the State Council also made a preliminary budget estimate, estimating that together with the construction funds, project funds, and the renovation of each member unit, it should be about 50 billion yuan.

However, Fan Wuxian also has his own statement on this, the large aircraft project is not only to focus on civilian flight aircraft, but also to consider that on this basis, it can be transformed into a military large aircraft, or directly develop a military system on this basis, in that case, the budget will increase a lot.

At the end of December, the general framework was erected.

However, now that I have sorted out the various units, I found that after more than ten years of delay, it has regressed a lot, and even some technical information during the development of Yun 10 can no longer be found, and many of the technical talents who made great contributions at that time have passed away, and many have changed careers, and the losses are quite serious.

"There has been a 20-year fault line in China's aviation manufacturing industry!" Fan Wuxian felt very sad.

In fact, the top management also hopes to repurpose the platform that developed the Y-10 back then. But now a look at it shows that there are many problems, and the cost of shrinking capacity is especially reflected in the engine of the Yun-10.

In the development process of the Y-10, in order to match, a factory in Shanghai successfully manufactured the engine used in the Y-10 on the basis of imitating the Pratt & Whitney JT3D turbofan engine of the United States. During the test flight of the Y-10, for the sake of safety, the Y-10 was equipped with the Pratt & Whitney engine used by the Boeing 707, and the imitation engine was installed on the Boeing 707 for test flight, which achieved very good results.

A 70-year-old aero engine expert at the Capital University of Aeronautics and Astronautics, answering the media how long it will take China to produce engines for large aircraft, said that of course it will not take 50 years, but it will take 30 years.

However, he also said that it was not easy for Shanghai to build a Pratt & Whitney engine back then.

According to him, the titanium alloy turbofan blades with tips made in Shanghai are now unable to be done by the entire Chinese aviation industry 20 years later, and the technical ability of Shanghai-made engines has completely disappeared, the plant and equipment have long been dismantled, and the personnel are no longer available.

Of course, there were those who ridiculed the engine as a copy, but that didn't diminish the significance of that achievement.

In fact. Jet engines were invented by Britain and Germany on the eve of World War II, respectively, and other countries started with imitations.

In 1941, the United States signed an agreement with Britain to copy British jet engines, and in October of the same year, Britain provided an unassembled engine and a series of drawings to the General Electric Company designated by the United States, and sent a technical team to assist the United States in copying it.

Even with such help, the engines copied by the American General Electric Company and their modifications did not catch up with the performance levels of British engines until early 1944.

The Soviet Union also began to develop jet engines before World War II, but it was not developed until the end of the war.

After the war, the former Soviet Union quickly copied jet engines with the help of German technicians, using captured German materials and equipment, and later purchased dozens of jet engines from Britain through trade negotiations and began to copy them.

The key to this question is not whether it is copied or not, but whether the technology has been learned. When the Americans copied the British jet engine, there were British technicians with drawings and technical materials to teach them by hand. In the process of imitating jet engines, the former Soviet Union moved German factories with personnel and equipment to engine industrial bases such as the Urals and Kuibyshev, gathered captured German technicians, and ordered them to provide technical knowledge, experience, and management methods.

In contrast, Shanghai was able to build a usable engine by reverse-engineering the original product by itself, and there must have been only a lot more technical learning.

It's a pity that the factory and the technicians and workers are all gone!

It is said that the day before the Yun-10 test flight, two vice ministers of the Ministry of Aviation Industry were in Shanghai, and one of them flatly refused to preside over the test flight ceremony, saying that it was impossible for the Yun-10 to go to the sky. If he went to heaven, he made a gesture of self-slaughter, which meant suicide to thank the world.

It's a pity that this deputy minister who threatened to commit suicide to thank the world broke his promise and became fat. After the success of the Yun-10 test flight, he did not wipe his neck, but the deputy minister who stuck to his post and personally presided over the Yun-10 test flight, and the chief designer of the Yun-10 aircraft, were depressed for a long time, accumulated worries, became ill, suffered from terminal illness, and passed away one after another.

At that time, a very well-known aircraft engine expert solemnly proposed to the central government that the project could not be stopped, the team could not be dispersed, and the results could not be lost. It is a pity that before the test flight of the Yun-10 aircraft, the decision to stop was made. The expert said with some regret, "Now it seems that the way of joint venture or cooperation cannot even solve the problem of simple automobile technology, let alone exchange the market for technology to get other people's aircraft engine technology, it is simply a fool's dream!" ”

If the Y-10 had persisted in carrying out the work at that time, then using this as a technological platform, the current large transport planes and strategic bombers would have already gone into the sky, and only then would they have a truly global strategic air force, and they would have taken much initiative on many issues.

"As far as the system parts of the Y-10 are concerned, they all use self-developed supporting products, and its landing gear is designed and manufactured by Shanghai itself, including an automatic anti-skid system. The technical difficulties are relatively large, and there is no problem in using them. Others include avionics, electrical systems, mechanical systems, etc., all of which are domestic. After the Yun 10 project was launched, many of these things were also halted or abandoned. The expert said to Fan Wuxi, "In the seventies, there were four major key projects, namely the 701 project (satellite project), the 708 project (Yun-10), the 728 project (nuclear power plant), and the 718 project (ocean-going survey ship). ”

The most distressing thing is that the technical team of the Shanghai factory that made the engine has been lost. In the past two years, the situation of state-owned enterprises has deteriorated, and the Shanghai plant has also gone bankrupt and dissolved because it has no business.

"Alas, no matter what, we must find these people to be the best, to build an engine, not only to have designers, but also the most important skilled technical workers, without them, this goal is also unattainable, many things, can not be copied on the drawings." The old expert said to Fan Wuxian.

Fan Wuxian nodded and said, "No problem, as long as these people are still alive, I will find a way to invite them back one by one!" ”

Almost everyone didn't believe that Fan Wuxian could do this, but Fan Wuxian soon began his own actions, and at his request, with the cooperation of CCTV, a documentary about the Yun-10 project was quickly made, and it was immediately broadcast continuously in prime time, and in the country's largest newspapers and magazines, they also began to discuss China's large aircraft project and the success or failure of the Yun-10 project that year.

After a week of publicity, during the advertising time after the news broadcast, a fifteen-second advertisement was inserted, the advertisement was very simple, in the background of the Y-10 aircraft, a line of big words typed out, all the participants in the engine project of the 708 project, whether you are a designer, or a skilled worker, or just a cleaner, and no matter where you are, what is the current situation, or you are entangled in mundane affairs. Or you are dying of old age, it doesn't matter, the important thing is that the motherland needs you! There are no pop-ups
